I noticed a few days ago that 2 text boxes can overlap without any warning -- that red overlapping icon does not appear..

A text box does not stick to the outline of i.e. another text box or layout region also..

I tried this with 2 layout regions.. When I resize a layout region with my mouse, when it is in a region close enough to another layout region, it sticks to it -- i have snap to object outlines chosen in the menu.

no way a text box can do this..
